Chambering Reamers and Headspace Gauges are available for every standard, custom, and foreign caliber. Chamber reamers are furnished in three basic sizes - Finish, resize, and rougher. Finish reamers are precisely ground to cut minimum size chambers and seating dies. Resize reamers are used as precise full length resizing die reamers and can double as precise roughers. Our Carbide Roughing reamers (core drills) are fantastic for fast stock removal in roughing out a chamber cavity before using the finish reamer.


We have 22,000 plus chamber reamer and gauge prints on file. If it's not listed, we can make it. Many wildcat and standard reamers & gauges are on the shelf for immediately delivery.
